Almons:walnuts:rasins=1:2:3


x=pounds of walnuts
y=pounds of almonds
z=pounds or rasins
2x=y

subsitute


12x+9y+5z=15
12x+9(2x)+5(3x)=15
12x+18x+15x=15
45x=15
divide by 45
x=1/3
so
1/3 pound of walnuts

2(1/3)=y=2/3
2/3 pounds of almonds

Airplane X left the airport, flying at a rate of 400 miles per hour. Airplane Y left 2 hours later, flying at a rate of 450 mile
sergij07 [2.7K]

Answer:   i think it will take 48 hours

Step-by-step explanation:

here's how to get 48 so basically 450-400-2= 48

now if you end up doing 400 - 450 then you will get -50 if you do 400-450-2 you will get a -52 <u><em>so you want to make sure you do the biggest number first and then do the smaller numbers to get 48</em></u> like 450 - 400 - 2 and then you will have 48

i hope this helps!

{1,2,3,...75,76,77,78}
Vinvika [58]

Answer:

32

Step-by-step explanation:

even numbers are 2,4,6,...,78

it is an A.P.

first term a=2

c.d. d=4-2=2

an=a+(n-1)d

78=2+(n-1)2

76=(n-1)2

n-1=76/2=38

n=38+1=39

now we take multiples of 10

10,20,30,...,70

70=10+(n-1)10

60=(n-1)10

n-1=60/10=6

n=6+1=7

so reqd. number of numbers=39-7=32

You need to buy a 20-foot length of 15-wide carpet that costs $29.50 per square yard. How much will this cost?
Marianna [84]

The cost of the carpet will be $983.33

<h3>Calculating cost</h3>

From the question, we are to calculate how much the carpet will cost

From the given information,

The carpet has a length of 20 feet

and a width of 15 feet

First, we will covert the dimension to yard

NOTE: 1 foot = 1/3 yards

Thus,

20 feet = 20/3 yards

and

15 feet = 15/5 yards = 5 yards

Now, we will calculate the area of the carpet

Using the formula,

Area = Length × Width

Area of the carpet = 20/3 × 5 square yard

Area of the carpet = 33.33 square yard

Now, we have that

The carpet costs $29.50 per square yard

∴ The cost of the carpet = 20/3 × 5 × $29.50

The cost of the carpet = $ 983.33

Hence, the cost of the carpet will be $983.33
